Article ID: KB21732 KB Last Updated: 02 Sep 2011Version: 1.0
Summary:
This article describes the procedure of checking the health of the RAID/disk on a NSMXpress 3000, when SMARTD is not running.
Symptoms:
Checking the Raid/Disk health on a NSMXpress 3000.
Solution:
The output below is when you check the status of SMARTD on the NSM3000 device:

[root@NSMXpress ~]# service smartd status
smartd is stopped

[root@NSMXpress ~]# service smartd start
Starting smartd: [FAILED]


SMARTD cannot query the Hard drives on a NSMXpress 3000, as they are in a RAID array.  Direct drive queries are not allowed.

A tool is available to check the status of the RAID array.  You can download the utility file, to install the tool, from the following link:

download.juniper.net/software/nsm/NSMXPress/asm_linux_x86_v6_50_18579.tgz

After the file is downloaded, perform the following procedure:
  1. Copy and Extract the .tgz file to any directory, such as:

    /tmp # cd /tmp
    # tar -xzvf asm_linux_x86_v6_50_18579.tgz

  2. Two directories will be extracted, namely cmdline and manager:

    # cd manager
    # rpm -ivh StorMan-6.50.i386.rpm


  3. After the installation is complete, run the following command to obtain the RAID status:
    # /usr/StorMan/arcconf getconfig 1  

    Example output of the command:

    The Important lines are:

    • Status of logical device : Optimal
    • And for Each drive: S.M.A.R.T. warnings : 0

    The output will be similar to the one shown below:

    [root@NSMXpress manager]# /usr/StorMan/arcconf getconfig 1
